Application elearniy 2o,`

To all iii/wm t may conce/ra.'

Be it lrnown that l, CHARLES P. R. Tinian, a` citizen of the UnitedStates, and a resident of North Andover, county of Essex, State ofMassachusetts" (whose post-oiiice address is .Prescott Street. NorthAndover, Mass), have invented an Improvement in (lone Dusters, of whichthe following description, in connection with the accompanying drawing,is a specification, like characters on the drawing representing likeparts.

This invention relates to a` cone Cluster, a machine which in itsgeneral characteristics is familiar to those skilled in the textile art'for cleaning or dusting all kinds of fibers, raw or treated. This typeof machine usually comprises a cabinet within which is mounted areticulated frusto conical cage through which the material. beingtreated is fed. A revolving beater frame provided with projecting pinsco-operating with fixed pins on the cabinet is mounted inside the cageand acts to loosen up the material `and shake or beat out the dustl anddirt. The .heavierdirt falls to the bottom of the cabinet and is removedfrom time to time while the lighter dust rising to the upper part of thecabinet sucked out by a suction fan.

One object of the present invention is to provide means for adjustinglongitudinal sections of the fixed pins in their angular relation to therevolving pins so as to vary the action of the pins on the material as.it passes through the machine. More particularlj.' this novel meansprovides sectional bars carrying the fixed pins so that any sec tion maybe rotarily adjusted to vary the angular relation of the pins withrespect to the opposed revolving pins. Thus, for eX- ample, the actionof the co-operating pins on the material at the commencement of theoperation maybe made less'severe than as the operation proceeds. i Thisminimizes the injury to the libres and maintains the maxif mum length ofstaple during the cleaning operation.

A further object of the invention resides in the decrease of the spacesbetween the cooperating teeth progressively toward the discharge end oflthe machine. This decrease may progress space by space or by successiveunits or groups of spaces. The result is also to produce a. less severeaction at the zo-operating teeth on the material GONE DUSTER.

during the earlier than during the latter stages of the operation.

A further object of the invention resides in the provision of mea-ns forsecuringr a `successive cooperation of the rows of pins,

so that no two rows on the heater frame shall simultaneously co-operatewith the rows of fixed teeth, and thus easing the action `on thematerial.

A further object of the invention resides in the improved constructionof the beater frame particularly in the provision of metal strapssurrounding and holding firmly in place the longitudinal bars containingthe projecting teeth of the rotating beater and in the means fortrussing or bracing the frame. This beater frame rotates at a high rateof speed-in the vicinity of 85() revolutionsiper minuteand this featureof the invention protectsiagainst the powerful centrif l actionresulting from this high speed of rotation.

A further object of the invention resides in the construction by mea-nsof which a continuous space is provided surrounding the cage between itand the cabinet so that the suction fan connected at a suitable point tothis space may remove all the lighter dust beaten out from the material.Heretofore, the space beneath the cage in the cabinet has been a deadair space and the lighter dust entering this space has been drawn backby the fan into the material and carried out with the material throughthe discharge opening to the detriment of the cleaning operation. Thepresent invention eliminates this serious objection.

These and other objects and features of the invention will appear morefully from the accompanying description and drawings and will beparticularly pointed out in the claims.

'In the drawings: i

The cone duster, as already pointed out, is a machine :tor removing thedust and dirt from librous materials of various kinds by.

a beating and combing operation during which the mass of libres ispulled apart and shaken up sothat the dirt and dust are beatenL out andthe fibres more or less straightened.

. Suche machine in the construction illustratedcomprises a large cabinetadapted to stand upon the iioor and made up of a. heavy fwooden framework and provided with enclosing walls. As illustrated, the end framesof the cabinet are similar. Each end trame comprises the vertical beams1, terminating at their upper ends in inclined beams 2, and connected atthe top by the cross beam A3. Transverse girders 4, .5 and 6 extend vatsuitable points horizontally between the vertical and inclined beams anda vertical strut 7 servesfto brace and support the center ot the girderbeneath the main shaft of the machine.

The end frames are connected by suitable girders extendinglongitudinally therebetween. As illustrated7 ythere are two of thesegirders 8 and 9 at the bottom oi" the machine connecting` the verticalbeams 1, and two at the top 10 and 11, connecting the upper cor- Thereare also two longitudinal girders 12 and 13 secured to the inner edgesof the vertical beams 1 at the front and rear respectively ot the trame.

The entire cabinet is closed except for the openings necessary forl thefunctioning of the machine. At the .top the cabinet is provided with apermanent cover A14: which may be secured to the girders 10 and 11 andeX-.

tend down the front 'and rear a short distance at 15 and 16. The suctiontan preferably` is mounted on this cover and connect-s therethrough bysuitable openings with the interior of the cabinet. .The tan casing 17is shown connected to side boxes 18 mounted on the cover 14 opening` atthe bottom into the cabinet and at the top into the fan casing. lVhilethe fan as shown is mounted on the top of the cabinet and connectingwith the upper portion of the space surrounding the cage it is'obviousthat it may be located at any suitable position, as for example upon thefloor and connect with the lower portion of the space. The fan which maybe of any suitable type isdriven by .a shaft 19 from a pulley 20connected to arsuitable source ofy power.

At the bottom the cabinet is closed in any 'suitable manner and as shownby the flooring 21 of the room in which it is located. The left hand ordischarge end of the cabinet, as shown in Fig. 3, is boarded up orotherwise closed between the Across beam 3y and glrders t, 5 and 6.Beneath the girder- 4under the action of the suction fan.

The front and rear side walls are preferably closed by hingedorremovable metal plates except at the openings providedfor .the admissionand discharge of the material.

As illustrated, a plate 26 hinged at 27 to the portion 15 of the coveris provided to cover the wall of the cabinet immediately above theadmission opening for the material. Another plate 28 hinged at 29 to thecover 15 serves to cover the remainder oiI the front inclined wall ofthe cabinet. The straight front wall of the cabinet is coveredpby alarge plate 30 and a small plate 31. The latter covers the section ofthe front wall beneath the admission opening and is removably held inplace by turn buttons 32. The iormer or larger plate 30 is hinged at 33in open bearing brackets 3a and held inI place at the bottomv edge Vb yturn buttons 35. Thus the plate 30 may be swung up and, whenkdesired,removed by lifting its hinged ends out ot the bearing brackets 34:. Theplate 28 is flanged and curved at its lower edge 36 so as to fit snuglyover the upper edge of the plate 30. f

The rear wall of the cabinet is provided with removable hinged plates 37on its verice tical surfaceA similar to the plate 30. The

inclined surface of the rear wall is provided at the discharge or lefthand end with a hoodl 33 forming the discharge opening for the materialwhile the remainder ot the inclined -surface is covered by a hingedplate 39 simi,-

lar to that on the front surface.

The cage through which the material passes while being treated is oftruste-coni cal shape with its smaller end terminating opposite thescreening 25, already described, and with its larger end against theclosed lett hand end Wall of the cabinet. This cage stnaported on thecross girders 6 at the ends oft the cabinet and* consequently incliningdownwardly toward the admission end.

lein intermediate.supporting structure is provided where necessaryaccording to the `the cabinet which at the upper Each such sectioncomprises a skeleton frame 13 supporting asection 414i of `Wirescreening. Each section or' thecage rests upon one of the cross bars atone end and upon the flange 42 of the central structure at the other endand thus can readily be removed by litting or removing; the proper coverplate of the cabinet. rlhese Vremovable sections of the cage are held inplace bythe turn buttons 46 carried by the girders 12 and 13.

`The lovver quarter sections ot the cage can,4 therefore, be slid outat' the front or rear of the cabinet to enable the heavy dirt depositedin the bottom ol lthe cabinet to be removed and the upper quartersections can be lifted out Whendesired tor the cleaning or repairing ofthe device. The 'front upper quarter section is constructed so as toprovide a suitable admission opening. As illustrated, this section abutsagainst one o?? the side frames 117 of the admission opening' intoportion vis covered by the'platea. f 9

The material to be treated is ted into` the canje through the admissionopenings of the cabinet and cage by a suitable teedingmeehanism. 'Forthis purpose an endless conveyor 49 is shown running` over a 'roll 50,

'From this conveyor the material is delivered to a. feed roll 51 carriedby the shaft 52 controlled by 'fast and loose pulleys il. licher-1n roll54; is mounted above the said roll l'and driven troni the shaittblfbycombed.. torn a1 art and shaken up by a plu;-`

ralityY of co-operatingpins. Sonie of `these pins are mounted in fixedposition, projecting); inwardly the periphery oi. the cao and Sonie arecarried upon the exterior riphery ot a rotating` beaterirame extendinglongitudinallyT through the center oi" the Cage. i i' In the preferredforni oit construction illustrated the fixed pinsare carried by aplurality ot sectional bars mounted and independentlyadjustable-rotarilyin the cabinet and extending longitudinally thereofand parallel with `the beater trame periphery and projecting into thecage. Thesesectional bars are conveniently mounted. on the zgirders 12,13 and i0 which, it will be seen),

i sary are arranged in general Way 120 degrees apart butvvith thespaceat the bottom between the girders 12 and 13 substantially ygreaterfor a reason hereinafter 'set forth.

Each sectional bar 56 is mounted and made rotarily adjustable in thesame manner and by similar means and hence it `Will be necesto describebut one in detail. For that purpose the one mounted on the girder 12 isselected and is shown in detail in Fig. 5. y

- be bar 56 is or' cylindrical shape and is seated in asemi-cylindricalrecess formed on in place at intervals by U-bolts 57surrounding the bar and` passing through the girder 12- and securedbythe nuts 58. The baroG made in a plurality ot sections. shown herein4as two in number separated at the point 59. The sections of the bar 56project through the end frames ot the cabinet and `each section isprovided with a radially pro- `seated .inua'countersinlr inthe face ofthe bar 56 and with `a shank G5 passing through the bar 56` and securedby nut 66 at the opposite tace of the bar. i

The beater trame is mounted on the main shaft 67 ot the machine which'is journalled inbearing blocks 68 ymounted on the cross bars 5 of theend 'frames over the vertical struts 7. This shaft isfcontrolled initsrotation by fast and loose pulleys 69 from a suitable source ot power:`Secured to the shaft (37 at suitable interi/*als are a plurality of castmetal spiders having; the radial arms orspoles 70 and the-peripheral"flanges 71. y'llhese spidersare provided with longitudinally alignedperipheral seats 72. preferably at the end of eachjspolre 70. and. inthese `seats are mounted bars 73 extending` lons-j.-`

tudinally ofthe beater frame 'from end to end. `Eachbar 73 carries aroiv oi.: pins rigidly `secured `to the bar, preferably in a similarlmanner to `that by which the ,pins 63 are secured to the bar These 'pins74 'projectraaially outward trom periphery oit the `beater trame. i

The beaterframe has a very considerable speedot rotation, in presentpractice about revolutions per minute. As it is a heavy structure, thereis l`f reat danger from injury to the machine it the parts oit thebeater are not'securely held against the` eentritue l 'torceresultingfrffrom the high speed ot rotation. Such daneer is eliminatedby :the inner face ol the `frirder 12 and is held Y progressive.

the means irovided in thisinvention for seneither equali'nor anevenmultiple-the one oli the other. lLooking,r i'or example, at thecuring the parteci" the beater trame in posivtion. `For this purpose ametal strap is pro! vided surrounding each spider and the bars seated'therein and `tiiisstrap is kmade circumterentially adjustable; Thedetails oi: a preferred torni et metal strap are illustrated in Figs. 1and 4 whereiny it will be seen that the metal strap 75 completelysurrounds the spider resting a.g 'aiiist itsperiphery and the outersurfaces cil the bars 7 3 seated therein.

,The ends: olf the stra-p `75 are preferably threaded at 76 and vunitedby a turn buclrle` 77 so that the strap may be circumterentiallyadjusted to ht snugly against the periphery of the spider and the bars73 seated therein.

YThis method ot securing the'bars 73 in the spider also provides a readymeans for removal and replacement of the bars and pms 'whenevernecessary.

The bars 73 are conveniently and preferably made of wood and may warp orloosen and disturb the shapel and balance of the beater frame slightly.ln order, therefore, to maintain the` desired rigidity of the revolvingbeater'lirame means are provided for trussing or bracing the trame. Forthis pur` pose vrthe hubs of the endinost spiders are shown as providedwith enlarged sections 78, see Fig. il, in which are-mounted the ends ota plurality. herein shown as 8, or rods 7 9. These rods at their middleportion pass through lugs or enlargements 8() near the `periphery ot thecentralspider of the beater frame.` Turn buckles 8l are interposed ineach rod 80 so as to enable each rod to be drawn up taut. Thus a verylirm bracing or true-sing oit the beater trarne is provided entirelyindependently or the bars 7 3.

Certain features with respect to the arrangementand operation of theco-operating l`fixed androtating pins which are provided by thisinvention'for the eiiicientaction on the material being treated areespecially to be noted. y

y nthe lirst place the pins are preferably arranged as illustrated inlongitudinal rows and the rows of fired pins are so related to the rowsvot revolving pins that no two cooperating sets function atthe same time.In other `words, the engaging action of the ro'- tating and linedpinsupon the material is This is secured by the `proper relative spacingcircumterentially of the cage and beater frame respectively of the rowsof iixed pins and movable pins. `,The paths'of rotation ot the pins onthe beater `trame, or the moving pins, pass between the pins on thecabinet, or the iXed pins,' so that' the material is beaten and pulledapart by the co-operativeengagement oftherows of pins in the usualmanner.

The particular feature ,et the invention referred to is secured, asillustrated, by making the spaces between the fixed rows of pins andtheintense spaces between Athemovable rows of pinsconstructionasillust'rated in -F ig. 4 and assumingr'that vthefbeater`trarne is rotating clockwise, it. will be seen that thel pins 711 attheupper left ofthe spider will co-operate with the pins on the bar 56in the girder 40, that next the pinsi'74 on the -lower left of thespider ,will co-operate with the pins on the bar 56 inthe girderv12andso` -on'successively in progression with no two sets co-operating atthe `same instant.v This result is secured .because7 as already noted,Vthe spaces between `thegirders 12 13 and 10 are not exactly 120rlegreest the space between the lgirders 12 and 13 being` greater andthespaces between the .ejirders 12e-.nd @and the girders 13 and l0 being'less ythan 120 degrees ywhereas the spaces between therows of teethonthe beater trame are ,all equal and as shown degrees. A f 'A In 'the'`second place the .pins both on the beater trame and on the xed bars areseparated longitudinally byA spaces decreasing in .length toward thedischarge end .of the rerchine, that is to say, the spaces Vbetween thepinsI are wider at the admission end than at the discharge end. Thisdecrease inthe spaces may progress'gradually or by '.units. The materialis thus acted on less harshly at the beginning Jthan at the end of theoperation. Atthe beginning of the opera.- tion the material is lmattedand full of dirt and this conditi-on is gradually diminished as thematerial passes through the machine. This feature assists also tdmaintain the Amaximum length of staple ofthe fibre `by 'controlling thevaction of the pins on the operating pins onthe beater frame and on thecabinet so as to vary their action on the material. This is preferablysecured by the rotary adjustment of the bars 56 in sections as alreadydescribed. Thus by adjusting the sections ot' the bars 56 at theadmission end so as to change the angle of the iXed pins with respect tothe revolving pins the action oit the co-operating pins on the materialat the beginning of the opera-tion can be made much less severe than atthe conclusion of the operation.

The operation of the machine will be apparent from the foregoingdescription. The material is fed in on the endless conveyer 4:9 throughthe admissionopeningsv of the cabinet and cageand is thoroughly beatenand cleansed by vthe co-operatingv pins of the beater frame and cabinetand iinally emerges through the. discharge opening 38. The action of theco-operating pins upon the material during its treatment is underperrect control by means of the threey features lll) just described. Theresult in practice is thoroughly to cleanse the material of dust`sections of the cage, shown in Fig. 6, and

rby cleaning out they space beneath the cabinet through the doors Qlandthe openings provided by the hinged plates on the front and rearvertical walls of the cabinet.

rlhe lighter dust is sucked out by the suction fan. By reason of theconstruction which provides a continuous space sur-- rounding the cagebetween it and the cabinet the lighter dust is sucked outiiroin allparts of the cabinet by the fan and is not drawn back into the materialand discharged therewith through the discharge opening as heretofore.This is an important feature of the invention. rlhere is no dead airspace beneath the cage. The lighter dust, both above and below the cage,is at all times under the control. ot the suction it'an because of thecontinuous space provided entirely around the cage between it and thecabinet.

Having thus described my invention, what l claim as new and desire tosecure by Letters Patent, is:
